We look at the division of 87242545 by 455 
We want to divide 87242545 by 455.

Step 1:
455 goes into 8 0 times with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Grab the next digit (7) from the dividend, add it to 8, then carry on: 87 / 455

Let's proceed to step 2:
If we divide 87 by 455, we get 0 and a remainder of 87.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 87 leaves us with 87.
Append the next digit (2) from the dividend to 87 and continue with: 872 / 455

Going ahead to step 3:
455 goes into 872 1 times with a remainder of 417.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 455 from 872 leaves us with 417.
Append the next digit (4) from the dividend to 417 and continue with: 4174 / 455

Let's proceed to step 4:
4174 divided by 455 is 9 with a remainder of 79.
Put 9 as the next digit of the answer. 
Result so far: 19.0
The remainder is 79 after subtracting 4095 from 4174.
Include the next digit (2) from the dividend after 79, then repeat: 792 / 455

Let's proceed to step 5:
455 can be fit into 792 1 times, resulting in a remainder of 337.
Put 1 as the next digit of the answer. 
Result so far: 191.0
Subtract 455 from 792 to get 337.
Grab the next digit (5) from the dividend, add it to 337, then carry on: 3375 / 455

Advancing to step 6:
If we divide 3375 by 455, we get 7 and a remainder of 190.
Use 7 as the next digit of our solution. 
Result so far: 1917.0
The remainder is 190 after subtracting 3185 from 3375.
Include the next digit (4) from the dividend after 190, then repeat: 1904 / 455

Moving on to step 7:
455 goes into 1904 4 times with a remainder of 84.
Put 4 as the next digit of the answer. 
Result so far: 19174.0
Subtracting 1820 from 1904 leaves us with 84.
Take the next digit (5) from the dividend and append it to 84, then repeat: 845 / 455

Advancing to step 8:
455 goes into 845 1 times with a remainder of 390.
Use 1 as the next digit of our solution. 
Result so far: 191741.0
Subtract 455 from 845 to get 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3900, and continue the process.

Advancing to step 9:
If we divide 3900 by 455, we get 8 and a remainder of 260.
Put 8 as the next digit of the answer. 
Result so far: 191741.8
If we subtract 3640 from 3900, we get 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

On to step 10:
2600 divided by 455 is 5 with a remainder of 325.
Put 5 as the next digit of the answer. 
Result so far: 191741.85
Subtract 2275 from 2600 to get 325.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3250, and continue the process.

Moving on to step 11:
455 can be fit into 3250 7 times, resulting in a remainder of 65.
Put 7 as the next digit of the answer. 
Result so far: 191741.857
Subtract 3185 from 3250 to get 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Going ahead to step 12:
455 goes into 650 1 times with a remainder of 195.
The number 1 becomes the next digit in our result. 
Result so far: 191741.8571
If we take 455 away from 650, we end up with 195.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1950, and continue the process.

Step 13:
The number 455 fits into 1950 4 times, leaving a remainder of 130.
The number 4 becomes the next digit in our result. 
Result so far: 191741.85714
Subtract 1820 from 1950 to get 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

On to step 14:
When dividing 1300 by 455, we get 2 with a remainder of 390.
The number 2 becomes the next digit in our result. 
Result so far: 191741.857142
Deduct 910 from 1300 and we're left with 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3900, and continue the process.

Moving on to step 15:
3900 divided by 455 is 8 with a remainder of 260.
The number 8 becomes the next digit in our result. 
Result so far: 191741.8571428
Subtract 3640 from 3900 to get 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Step 16:
If we divide 2600 by 455, we get 5 and a remainder of 325.
Use 5 as the next digit of our solution. 
Result so far: 191741.85714285
If we subtract 2275 from 2600, we get 325.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3250, and continue the process.

The final result is 191741.85714285 with a remainder of 3.25e-07.
